The paper considers two concepts of the iodine storage and supply system for electric thruster: for ground-based experimental research of iodine electric thrusters and for their possible application in space. Both concepts are developed with regard to low energy consumption. The results of experimental research of both concepts are also provided with maximum iodine consumption rate (15 mg/s for the ground option, 4 mg/s for the space option of iodine storage and supply system). The ground option was controlled by two procedures: while maintaining the constant temperature of the iodine container; and while maintaining the constant outlet pressure of the iodine container. The iodine storage and supply system option for space application was controlled only while maintaining the constant temperature of the iodinetank. The upgraded design of the storage and supply system is described with increased efficiency through the heat supply in the iodine evaporation area, as well as with an increased iodine flow rate stability in the electric thruster through addition of a receiver locateddirectly behind the iodine evaporation area. The paper also presents the iodine storage and supply system developed by US company Busek Co.
